Abstract
A mixture layer for an electrode is formed on a punched current collector. For example, the mixture layer is made of an active material, conductive assistant, binder, and the like. The mixture layer having the structure described above is formed into a slurry, for example, and applied onto the current collector. The applied mixture layer is dried to fabricate an electrode. The thus formed electrode is used to assemble an electric storage device. Upon the assembly, lithium ions are pre-doped into a negative electrode. The pre-doping time is determined according to air permeability of the electrodes.
